Thermal Stability and Irradiation Resistance of (CrFeTiTa)70W30 and VFeTiTaW Hi...

ABSTRACT: Nuclear fusion is a promising energy source. The International Thermonuclear Experimental Reactor aims to study the feasibility of tokamak-type reactors and test technologies and materials for commercial use. One major challenge is developing materials for the reactor's divertor, which supports high thermal flux. Tungsten was chosen as the plasma-facing material, while a CuCrZr alloy will be used in t...

Mecanismos combinados na apneia central do sono: contributo da obesidade e dos ...

Enquadramento: O uso crónico de opioides compromete a quimiossensibilidade central ao dióxido de carbono (CO₂) e oxigénio (O₂), favorecendo a instabilidade ventilatória e podendo levar à Síndrome de Apneia Central do Sono (SACS) [1]. Descreve-se o caso de uma mulher de 40 anos, fumadora, com índice de massa corporal (IMC) de 38,1 kg/m², em programa de substituição com metadona, referenciada para consulta de Pat...

First molecular detection of Mycoplasma agassizii in captive tortoises in Portugal

Introduction: Mycoplasma agassizii is a well-recognized etiologic agent of upper respiratory tract disease in tortoises. Although frequently reported in both captive and wild populations across Europe, its occurrence in Portugal had not been previously documented. This study aimed to investigate the presence of M. agassizii in apparently healthy captive tortoises in mainland Portugal and to evaluate potential h...

Submerged villages in Portugal: Vilarinho da Furna, Aldeia da Luz and the “othe...

Portugal has two paradigmatic cases of dam-induced displacement: Vilarinho da Furna, submerged in 1972, and Luz, in 2002. Although research regarding these two case-studies has occasionally mentioned the existence of several other similar events, those have not yet merited dedicated research. This void in the bibliography suggests Vilarinho and Luz are isolated episodes, obscuring their place as part of a wider...

The rehabilitation of women who have had a mastectomy

Background: Breast cancer is one of the main causes of mortality among women, and mastectomy has a significant effect on the body image, sexuality and psychology of women. The aim of postmastectomy rehabilitation is to improve functionality, minimize complications and promote well-being and quality of life. Objectives: This study aimed to understand the role of nurses specializing in rehabilitation nursing in t...

The dolmen of Monte Serves (Vialonga, Vila Franca de Xira, Lisbon): architectur...

The dolmen of Monte Serves, located in Vila Franca de Xira (Lisbon peninsula), corresponds to a small megalithic tomb with a trapezoidal plan built using limestone slabs. It was identified in 1972 by Octávio da Veiga Ferreira, being excavated that same year under the direction of Christopher Thomas North. In 2014, within the scope of the project MEGAGEO – Moving Megaliths in the Neolithic, this monument was the...

Bacterial cellulose nanocrystals or nanofibrils as Pickering stabilizers in low...

This investigation assessed the potential of bacterial cellulose (BC) in two distinct forms, nanocrystals (BC-NC) and oxidized nanofibrils (BC-NF), as stabilizers for low oil-in-water emulsions (1 % v/v). The research explored the impact of ionic strength and BC concentration on the physico-chemical characteristics, stability, and rheological properties of those emulsions. Nanofibrils had diameters ranging from...

Examining local action groups as territorial development polities: CLLD in Lisb...

Over the past three decades, Local Action Groups (LAGs) have gained significant relevance as territorial development polities. Initially established in the 1990s under the LEADER programme, EU-funded LAGs were lauded for their ability to engage local stakeholders, promote proactivity, and build capacity for designing and implementing Local Development Strategies (LDS). With the introduction of the Community-Led...
